Help. My Boxster S 987 has decided it doesn't want to leave the garage and the brakes, the rear ones I think, seized up after I'd reversed a few feet. That is to say the car refused to reverse any further despiterevving the enginevquite a lot. I'm guessing it;s the brakes - there is nothing on the garage floor impedingthe car's progress. The car has done c109,000 miles and has been sat on a trickle charger for c2 weeks after a return from Wales to south London in rainy weather. I'm wondering if this kind of problem has occurred before and if the fix is straightforward?

Any help would be much appreciated.

Try pulling forward, then back again a few times. The rocking back and forth should unbind the brake(s). Or just give it plenty of throttle in reverse...

PS and don't leave the handbrake on in future wink Just put it in gear.

Very discombobulating :-) I'll try the rocking.

Did you park with the handbrake applied? Likely the shoes have bound themselves inside the disc drums particularly if it was parked up after being wet.

Can you jack up each rear wheel and , out of gear , try turning the wheel ? Remove each wheel and strike the hub of each disc with a hammer to try and break the grip of the shoes.

Let the car idle for a good while and the heat transferred to the drums plus a little more rocking could free them up.

The handbrake shoes have probably fallen to bits if it moved a bit, then locked up. Gonna have to take it apart / get it recovered I'm afraid.

Is there a mark on the ground where one wheel was dragged? if it did roll normally both sides initially it must be what Lar Jammer says - or worse something in the transmission....

Maybe the ABS has a fault

Thank you for these suggestions - some of which are frightening such as broken handbrake shoes. Freeing each wheel in turn sounds worth a try. However a garage is coming to pick it up so they can can work the problem.

It’s usually the parking brake.

Had this a few years back on mine, after foolishly taking it to a non-specialist to replace rear discs & pads. Left a few weeks with the parking brake off, and they still seized on. Trailered away to someone who knew what they were doing, problem solved. I always take it for a ‘brake drying run’ after I’ve washed it though.

Sounds very much like delaminated handbrake shoes, does your handbrake have the same travel / feeling as normal? The delaminated material can jam near the actuator and make the handbrake travel less rather than more as expected.

I cant remember if it was the 987 or the 981 but one of them had a problem with the brake peddle sticking, it was something to do with when you pressed the brake there was a tube (or something) that stuck so the brake would not release.
I had to put my foot under the brake peddle and lift up to release the brake.
Just a thought.

It's fixed. The handbrake barke pads had attached to the disks. Attempting to rock the car backwards and forwards failed, until a recovery guy tried on a particularly cold morning and freed them after a graunching noise. Weston Porsche in Beckenham found that the brake pads had disintegrate dinto bits and one spring was broken. So, £450 later plus the recovery fee, I have a repaired Boxster. Phew!!

The lesson from this is that after a long drive in the rain do not leave your Boxster handbrake on for 2 weeks.

Thank you again for all the positive suggestions and help.
